Before upgrading your Cisco Cloud APIC software, follow the instructions in this topic to locate the existing configuration information for certain fields and make a note of the entries for each of these fields. You will use the same entries for these fields below, in a step later in the following procedures, when you use the Release 5.1(2) recovery template to upgrade your Cisco Cloud APIC.
For each of the following fields, make a note of the entries that you entered as part of the original deployment that you performed inDeploying the Cloud APIC in Azure, on page 30:
•Subscription, on page 83
•Resource Group, on page 83
•Location, on page 84
•Fabric Name, on page 84
•External Subnets, on page 85
•Virtual Machine Name, on page 85
•Infra VNET Pool, on page 85
•Storage Account Name, on page 86
